摘要:
A method and apparatus for transmitting information while correcting bursts of errors is described. The technique uses a calculation of coefficients of code words by obtaining polynomials from the factorization over a field of elements. On transmitting, a product of a plurality of polynomials is obtained and this product is divided by another polynomial to obtain coefficients. On reception, a reciprocal of the polynomial is used and coefficients are also calculated. By summing the most significant coefficients of the polynomials, corrected bits of the message are obtained.
